The production of Th and U requires the separation of these elements from rare-earth elements (REEs) as they often coexist in various feedstocks. Equally crucial is efficiently isolating scandium (Sc) from REEs, considering its high-value status and pivotal role in advanced alloy technologies. This study introduces a new selective ligand-functionalized silica sorbent for extracting Sc, other REEs, Th, and U from solutions with varying pH and elemental compositions. The functionalized sorbent exhibits exceptional selectivity for Sc ions at pH 4 across solutions containing 3–20 elements. It also shows excellent selectivity for Th at pH 2 in 18- and 20-element solutions and substantial selectivity for U in 18- and 20-element solutions at pH 4. Additionally, it efficiently adsorbs neodymium (Nd), dysprosium (Dy), and lanthanum (La) in Sc-free solutions with a given preference for Nd. The ligand-functionalized sorbent successfully undergoes ten cycles of reuse which along with its enhanced recovery performance toward targeted elements highlights its industrial application potential.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"73 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glioblastoma (GBM) is a major challenge in oncology due to its highly invasive nature and limited treatment options. GBM's aggressive migration beyond tumor margins and rapid tumor growth hinders success in patient treatment. Localized therapeutic delivery, such as the use of transition metals like copper, is highlighted as a novel therapeutic agent for many potential biomedical applications. Herein, it is aimed to study the effects of Cu release on the proliferation and invasiveness of cancer cells. To this end, novel copper-based nanostructures with different release patterns are designed. Using a complex 3D cell culture model to mimic the tumor microenvironment, it is shown that different patterns of copper ion release have a strong impact on GBM progression and invasiveness. The findings highlight the importance of optimizing localized copper release patterns to tailor different tumor treatment strategies. They also show the potential and suitability of 3D microchips as instruments to study the behavior of tumor spheroids. In spite of their limitations, these 3D microdevices enable a controlled and close monitoring of the influence of environmental factors (such as the presence of Cu ions) on the proliferation and invasiveness of the cells, with a better approach to reality compared to 2D models and with a more controlled environment, compared to an in vivo model.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"7 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These engineered nanocomplexes are designed to deliver sufficient PTX molecules into a targeted solid tumor in a light-controllable manner while inducing significant photothermal and antitumor immune responses. The outstanding photothermal conversion property of the CNHs under near-infrared light enables effective cancer cell ablation and awakening of cytotoxic immune responses. Tumor cell membrane-coated CNHs show improved water dispersibility, immune evasion, and targeting capabilities alongside enhanced immune activation against tumors. The efficacy of the biomimetic functional CNH nanocomplexes is demonstrated through excellent tumor-targeting, controlled drug-releasing behavior, and induction of cancer cell death, contributing to a robust antitumor response.

Herein, a simple and fast microwave-assisted method for preparing high-quality nanosized PCN-222 crystals and their metalated derivatives PCN-222(M) is reported to finely tune the sensing response. Next, the successful dispersion of these PCN-222(M) nanoparticles into poly(dimethylsiloxane) to create flexible and transparent membranes is demonstrated.

However, current DNA-based data storage systems are incompetent of achieving high-quality random multiplexed access and frequently accessed data storage, which impedes its practical applications. Here, a dual-mode storage system is proposed that combines DNA-based archival data and nanodot-based active data. This novel data-storage system is constructed by writing the active and archival data on the same substrate through a facile two-step process involving scanning probe lithography (SPL), DNA synthesis, and chemical immobilization. The data files are categorized and stored orderly in different microregions of the substrate to achieve efficient random access. On each microregion, the nanodot array stores not only the concise information for the archival DNA data but also contains the corresponding primer sequence. Such interrelation between active and archival data allows for facilely data reading by efficient microscopic modalities and in situ polymerase chain reaction (PCR). Facilitated by the integration of nanodot and DNA, this novel dual-mode storage system demonstrates efficient data access and the potential of excellent storing capacity, paving the way for the advancement of DNA-based data storage.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"97 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ITC@ZrO(TocP)/ZrO(FdUMP) core@shell nanocarriers (designated ITC-FdUMP-NC) with the clinically relevant chemotherapeutics irinotecan (ITC) and fluoro-2′-deoxyuridine-5′-phosphate (FdUMP) (active derivative of 5′-fluorouracil/5-FU) are a new type of nanocarrier with high drug payload (22 wt% of lipophilic ITC: particle core; 10 wt% of hydrophilic FdUMP: particle shell).

Fluorescence-labeled nanocarriers show efficient uptake by all CRC cells and allow to distinctly track the intracellular trafficking toward endolysosomal compartments.

The sustained drug-release profile of the nanocarriers contrasts favorably with conventional free drugs, potentially enhancing the therapeutic outcome in vivo.

Herein, a particle fractioning method is proposed, which is suitable to differentiate between polymer-grafted microparticles that are equal in size. The separation relies on the combination of a pressure driven microfluidic flow, together with simultaneous light illumination and temperature control. Heating the solution forces thermo-responsive surface grafts to undergo a volume phase transition and therefore locally changing the interfacial properties of the microparticles. Light illumination induces the phoretic/osmotic activity of the microparticles and lifts them into a higher plane, where hovering particles experience a different shear stress proportional to the height. The light-induced hovering height depends on the interfacial properties, and this complex interaction leads to different movements of the microparticles as a function of their surface grafting. The concepts are visualized in experimental studies, where the complex physical principle provides a simple method for fractioning a binary mixture with at least one thermo-responsive polymer graft.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"60 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
